The requests are directed to ban the President from signing the laws adopted by the Bundestag and the Bundesrat on the 29th of June 2012 as measures to tackle the sovereign debt crisis in the euro area until the decision on the particular main decision.

The court will either decide the law can be put in force or it will decide there must be a ruling in the matter (next year or so). I find the former is more likely. The court will NOT decide on the constitutionality next week.

Unless some sort of loophole is found, yes. The court is aware of that, though. I don't believe they will decide on (another) stay. And that means Merkel's strategy of postponing a decision until it is too late for a meaningful debate will have won again.
